Apple will announce a new Readiness app during its “Surprise and Shine” event this Wednesday at 10 a.m. Pacific Time. This places a built-in recovery scoring system as a free alternative to specialized fitness trackers like Oura and Whoop.
According to Bloomberg’s Mark Gurman, the app will function as a variant of Apple’s existing Vitals app, which launched on watchOS 11 and consolidates key health metrics including heart rate, respiratory rate, blood oxygen, wrist temperature, and sleep duration. The new app will calculate how recovered your body is for activity, using many of the same underlying data sources. Oura’s smart rings offer a daily “Readiness Score” from 0 to 100 that signals how prepared your body is for the day; Apple’s implementation follows a similar scoring model but requires no separate device or subscription.
The Readiness app’s existence was uncovered days ago by MacRumors forum member “pdfu” in watchOS 27 and iOS 27 beta code. The app appears as a separate Watch application distinct from Vitals, positioned immediately after the Workout app in the default Home Screen layout, a placement that suggests Apple considers readiness monitoring as core fitness functionality, not an ancillary feature.
What Powers the Readiness Score
Continuous heart rate sensing, available on both the Series 12 and Ultra 4 regardless of whether you are actively exercising, could provide the data foundation for meaningful readiness calculations. This step beyond the Apple Watch’s current passive health monitoring approach and directly addresses the gap that has allowed Oura and Whoop to build loyal user bases among fitness enthusiasts and athletes.
Apple is also introducing new optical sensor hardware codenamed “Sunstone4p0,” featuring lower noise coefficients and wrist- and orientation-based channel selection. This revised heart-sensing architecture improves accuracy during weak pulse signals and adapts sensing based on how the watch is worn, strengthening the quality of data feeding into readiness scores.
Hardware Improvements and Storage Boost
Both the Series 12 and Ultra 4 is expected to feature double the storage of previous models. The specs include:
- Storage capacity: 128GB, up from 64GB on Series 11 and Ultra 3
- Purpose: Supports local health data processing and retention
- Design: No major changes compared to Series 11 and Ultra 3
- Touch ID: Not included on either model
The storage increase directly supports on-device health data processing. This suggests Apple’s strategy to keep sensitive analytics local rather than relying on cloud infrastructure.
Why This Shift Matters for Fitness Users
Readiness scoring has remained the domain of premium third-party services, kept behind paywalls and separate hardware purchases. By folding this functionality into watchOS as a native, pre-installed app, Apple removes the friction and cost barrier that has kept mainstream users from adopting science-backed recovery tracking. Existing Vitals users already collect the raw data but the Readiness app simply transforms that data into actionable daily guidance, accessible without a subscription.
For casual fitness fans and serious athletes alike, a built-in readiness score tied to a system they already use eliminates the need for a separate wearable purchase. This shows that Apple views fitness and recovery analytics as central to the Apple Watch’s future, not optional extras.
